FIELD OF THE INVENTION

The invention relates to a brewing sachet for brewing tea or tea-likesubstances, with a fluid-permeable envelope which contains the tea ortea-like substances, and with a holding element arranged on theenvelope.

BACKGROUND OF THE INVENTION

Brewing sachets which are suspended into a hot fluid by way of a threadfastened on the upper side of the bag are known. The disadvantage ofthis, amongst other things, is that the thread may easily drop into thefluid.

Other brewing sachets which relate to the type according to thisinvention, have no thread. Instead, they are provided with a strip ofcardboard, which serves as a holding element and by way of which thesachet may be suspended on the edge of a vessel and may be located inthe hot fluid. If one orders a brewed drink, such as in particular tea,in a cafeteria, then the person placing the order receives a cup, a mug,a small pot or a glass with hot water, into which a brewing sachet withtea or tea-like substances is immersed, or into which an attachedbrewing sachet may be immersed. In order for the tea to develop itsoptimal taste, the brewing sachet must be removed after a certain time,and placed on a provided saucer.

In recent times, more and more fast-food restaurants and coffer bars areappearing, in which take-away drinks are bought in a disposable cup andare taken away for consumption. This is possible in a simple manner withcoffee, but for taking away tea drinks, there exists of problem of beingable to remove the brewing sachet from the fluid. Usually, when walkingor driving an automobile, there is no possibility for putting down thebrewing sachet or disposal of this. Moreover this would demand acumbersome handling.

For this reason, a mug lid for hot drinks has been suggested in theGerman utility model document DE 20 2005 008 816 U1, which has a cavity.A suspended brewing sachet is then pulled into the cavity of the lid.The disadvantage with regard to the lid is the fact that it must bemanufactured in a complicated manner, which significantly renders thedisposable cup more expensive. A further disadvantage is the fact thatfor manufacture, one requires more plastic material than forconventional lids, by which means the environment is burdened to agreater extent.

SUMMARY OF THE INVENTION

It is therefore the object of the present invention, to suggest abrewing sachet for brewing tea or tea-like substances, with afluid-permeable envelope which contains the tea or tea-like substance,and with a holding element arranged on the envelope, which is suitablefor take-away drinks or likewise, without any special external devicebeing required for this.

This object is achieved in that a pull device is fastened on theenvelope. The envelope with the tea or the tea-like substances may bepulled to the top by way of the pull device, and may thus be removedfrom the fluid. The brewing sachet itself thereby may advantageouslyremain suspended on the vessel.

The object is furthermore achieved in that the holding element extendsroughly up to the lower edge of the envelope. If, after the removal ofthe brewing sachet from a vessel, the holding element is pressedtogether at its side edges, then with this, the envelope with the tea orthe tea-like substances is pressed out. In this manner, residual fluidexits from the brewing sachet and is used. A dripping of the brewingsachet is furthermore prevented.

A thread is provided as an inexpensive pull device.

A laminar body, in particular a cardboard strip, is provided as aholding element. The cardboard strip is likewise manufacturable in aninexpensive manner and may be printed with a characterization or otherdetails.

An opening for the leading through the thread is provided on the holdingelement. The opening forms a guide for the thread, which by way of this,may be pulled away from the vessel in roughly the radial direction.

The holding element comprises a notch for firmly pinching the thread.The envelope may be held in a position outside the fluid in an improvedmanner by way of this.

A holding tag is provided at the free end of the thread. The thread maybe gripped in a secure manner by way of the holding tag.

The holding tag may be releasably fastened on the holding element by wayof the holding element having an adhesive agent for the holding tag. Byway of this, it does not hang down on the holding element.

The pressing-together of the holding element and the pressing-out of theenvelope which is effected by way of this, are simplified by way ofproviding at least one, preferably two vertically extending crimps, forthe holding element. Furthermore, with this, the brewing sachet adaptsbetter to the usually arcuate wall of vessels.

The envelope in its upper region comprises a capillary brake, inparticular a weld seam, which prevents the rising of fluid. By way ofthis, one avoids fluid getting to the upper edge of the vessel via theenvelope, from running down the outer vessel wall, and leading to amess.

The brewing sachet according to the invention is in particular suitablefor a drink for taking away. With regard to drinks for take-away, thedrink is mostly filled into a disposable cup, for example of cardboardor polystyrene, and closed with a plastic lid which may comprise adrinking opening. The drink may not be so easily spilt with the lid, andis kept hotter for longer. The brewing sachet is suspended into such adisposable cup, thereafter hot water is filled into the cup, and thenclosed with a fitting closure lid. With this, the holding element isarranged on the outer wall of the cup, and the envelope with the tea orthe tea-like substances is arranged in the inside of the cup. After thebrewing time is completed, the holding tag is released and thus thethread is pulled out. By way of this, the envelope in the inside of thecup is pulled upwards out of the fluid and pressed at the same time. Thethread is pinched into the notch and thus fixed, by which means theenvelope remains outside the fluid surface.

The brewing sachet according to the invention is further in particularsuitable for small tea pots. Small tea pots are often used inrestaurants and hotels. With this use, the brewing sachet is suspendedinto the small tea pot, wherein the holding element is arranged on theouter wall, and the envelope with the tea or tea-like substances isarranged in the inside of the small tea pot. After the suspension, wateris added and the small tea pot is closed with the associated lid. Afterthe brewing time is completed, the holding tag is released and thethread is pulled out with this. By way of this, the envelope in theinside of the small tea pot is pulled upwards out of the fluid and atthe same time is pressed out. The thread is pinched into the notch andthus fixed, by which means the envelope remains outside the fluidsurface.

The brewing sachet according to the invention is furthermore suitablefor cups and mugs of porcelain or ceramic. Often, such vessels are usedat the bar. For this application, the brewing sachet is suspended intothe vessel of porcelain or ceramic, and hot water is then filled intothe vessel. With this, the holding element is arranged on the outer wallof the porcelain cup or glass cup, and the envelope with the tea or thetea-like substances is arranged in the inside. After the extraction timeis completed, the holding element is gripped and the brewing sachet isremoved from the porcelain cup or the glass cup.

DETAILED DESCRIPTION

FIG. 1 shows a perspective rear view of a preferred embodiment of thebrewing sachet 1 according to the invention. The brewing sachet 1comprises an elongate, bag-like and water-permeable envelope 3 whichcontains tea or tea-like, aromatic substances. The envelope 3 is closedat its lower side and consists of filter paper or a gauze material. Aholding element 2 which consist of a strip of cardboard is arranged onthe envelope 3. The holding element 2 has different functions. Its lowerend is designed in an arched manner, by which means an aesthetic effectis achieved. The other end is turned over to the rear, and thus forms aclosure tab 14 which closes the envelope 3 at its upper side.

With the shown embodiment of the brewing sachet 1, the holding element 2extents roughly to the lower edge of the envelope 3. By way of this, onemay press out the envelope 3 with its aromatic substance in aparticularly simple manner by way of pressing together the holdingelement 2 at its two side edges. In order to simplify the pressing-out,the holding element 2 has two vertically running crimps 12.

Furthermore, a square opening 5 with a notch 56 is present on theholding element 2. The opening 5 is partly covered by the closure tab 14and a region of the envelope 3. A thread 4 is led through the opening 5from the front side. The other end of the thread 4 is fastened on thelower side of the envelope 3. The envelope 3 with the aroma substancesmay be pulled to the top by the thread, and may thus be removed from thefluid. The thread 4 is firmly clamped by way of the notch 6, and thusthe envelope 3 is fixed in the pulled-up position. The type of notch 6is however not limited as is represented in FIG. 1. In anotherembodiment which is not shown, the notch 6 is for example located at theupper edge of the holding element 2.

The envelope 3 at its upper region furthermore comprises a welding seam11 which serves as a capillary brake and thus prevents the rising offluid. By way of this, one avoids fluid from getting to the edge of thevessel (not shown) by way of the envelope 3, and running down its outerside in an annoying manner.

FIG. 2 shows a perspective front view of the brewing sachet 1 which issuspended into a cup 15. With regard to the cup 15, it is the case of adisposable cup of cardboard, as is used for example in fast-foodrestaurants and coffee shops. The brewing sachet 1 is suspended into thecup 15 by way of the holding element 2, for brewing, wherein its wall islocated between the envelope 3 and the holding element 2. The holdingelement 2 thereby has an additional function as a grip, so that afterthe brewing, the hot and wet envelope does not need to be touched formoving or for the removal.

FIG. 2 furthermore shows the one end of the thread 4. This is fastenedon the lower side of the (not visible) envelope 3 and is led through theopening 5 to the front side of the brewing sachet 1. A square holdingtag 7 of paper or thin cardboard is fastened at the end of the thread 4.The thread 4 may be better gripped and pulled by way of the holding tag7.

The holding element 2 in the upper region comprises an opening 5. Theopening 5 is covered on the rear side of the holding element 2 partly bythe tab 14 and the envelope 3. An adhesive element 9 is arranged in thisregion of the opening 5 which is covered by the closure tab 14 and theenvelope 3. The holding tag 7 may be arranged on the holding element 2in a releasably adhesive manner by way of this adhesive element. In FIG.2 however, the holding tag 7 hangs on the thread 4 and is not fastenedon the holding element 2. The opening 5 comprises a notch 6. The thread4 is firmly pinched into this notch 6.

The holding element 2 comprises two crimps 12 running from its upperedge to its lower edge. The holding element 2 may be creased slightlydownwards along this crimp 12. By way of this, the brewing sachet 1adapts well to the curvature of the wall of the cup.

The front side of the holding element 2 is printed with acharacterization 10. Numerous other details or advertisements may beprinted on account of the large surface of the holding element 2.Moreover, the holding tag may additionally be printed.
